COOKING-STOVE.

Specification lof Letters Patent No. 211,900, dated October 26, 1858.

.Figure l, 'denotes :a side elevation of the l said stove; Fig. 2, alongitudinal, Verticall and central section; Fig. 3, a horizontalsection taken through the grate, f,fof the ireplace; Fig. 4, ahorizontal section taken through the openings for leading hot air intothe oven; Fig. 5, a vertical and transverse section of the air passagesin rear of the oven. Fig. 6, is a top View of the stove.

The nature of my invention or improvement consists as follows: lst, in acombination and arrangement of smoke iiues carried about the oven andair passages or flues arranged against the smoke fines so as to absorbthe heat radiated therefrom and conduct it into the oven. Next, in thearrangement by which the fireplace back is made to receive air, heat thesame and conduct it into the oven. Next, in a peculiar air guard appliedin the upper smoke ue and with respect to an air register and thedischarge pipe as hereinafter described.

In the said drawings, A, denotes the outer case of the stove lined withplaster of Paris or other suitable material and having an arch, B, afire place or re box, C, and an ash-pit disposed within it as shown inthe drawings.

In front of the fireplace is what may be termed a hollow back E, whichhas an arched top a, and by means of a passage, I), leading from belowthe arched top communicates directly with the interior of the oven. Thesaid hollow back, E, has an opening, c, at one end out of one side ofthe stove as shown in Fig. 3, the same being to enable atmospheric airto pass into the hollow back and after becoming heated therein todescend through the passage Z), and enter the oven. The ireplace is tobe supplied with fuel through the front boiler openings F, F, arrangeddirectly over it and in the .top plate, d, of the stove, other boileropenings F', F, being arranged in the said top plate as shown in thedrawings. The Ygrate 1s shown at a.

Fig. 7, is a vertical and transverse section i vtaken thorugh thedampers of the iire place,

and upper smoke flue, `exhibited lat e, e, as applied to the passages,f, f, of communication between the iire place and the upper smoke flue,Gr, arranged directly `underneath the front boiler openings, F, F, asshown in the drawings, a discharge flue H, being led vout of said uppersmoke flue. WT hen the dampers, are open, the smoke from the iire placewill pass ofi' through "the passages, 7, 7", and into the upper smokeiiue without going around the oven, but when the dampers are closed, thesmoke Aand heated volatile products of combustion from the re place willbe made to pass over the arched top,, thence downward into a flue I,arranged along the front of the oven and continuing underneath thebottom such vdampers Ibeing thereof and opening into a series ofvertical flues, K, K, K, applied to the rear end of the oven and made toopen into a flue space, L, disposed on the top of the oven and by meansof suitable passages g, 7a, made to open directly into the smoke flue, G

Air passages or iiues M, M, are placed between the Vertical fiues K, K,as shown in the drawings. Each of said air passages M, opens at itslower end by an orifice, i, directly into the oven, while at its upperend and by an oriiice, c, it communicates with a vertical air space, N,arranged as shown in the drawings. The said air space N, at its upperend opens into an air space O, arranged against the outer surface of thesmoke flue, L, and having one of more openings, Z, disposed in its upperpart, such openings being for the reception of air which when the stoveis in operation will pass through the space O, and against the smokeflue, L, thence into the air space, N, thence down the passages M, M,and into the oven. Such air during its passage receives radiated heatand finally discharges the same into the oven for the purpose offacilitating the operation of baking therein.

By my said arrangement, it will be perceived that the oven not onlyreceives heat from the flue L, but from air heated and led into it inmanner described both from the air space about the fines of the oven aswell as that in the fire place back.

A pipe, P, extends out of the top of the oven, and up to or through thetop plate of the stove and is there provided with a register m. Thispipe also has an opening n, through its front side, such opening beingfurnished with a slide valve, 0. By means of the pipe, P, the register,rai/,the opening, f/L, and the valve, o, thereof, the heated air of theoven may be either discharged into the room in which the stove may besituated, or caused to pass into the upper smoke flue, Gr, as occasionmay require. Furthermore, the top plate of the stove near the dischargelue, H, is furnished with a series of openings, p, p, 72, and a slidingvalve, r, adapted to the said openings, a bent plate or air guard, s,being extended from the top plate of the stove and with respect to theopenings p, p, as shown in Fig. 2. The said air guard operates toprevent the smoke from passing out of the openings, p, p, and insuresthe passage of air into the same and the discharge flue, when such maybe necessary in order to facilitate the draft of the tlues.

Having thus described my improved stove,

.I would remark, that what I claim therein .is as follows,

l. I claim the combination and arrangement of the hollow back, E, of thefire place, With the oven, B, the fire place, C, and the lue, I,`whereby the heat of the fire place and the said lue is made to Warm theair which passes into the hollow back such air being subsequentlydischarged into the oven as described.

2. I also claim the combination and arrangement ot' the smoke ues, I, K,K, K, and the air lues, O, N, M, M, the Whole being disposed withrespect to the oven essentially as hereinbefore described.

3. I also claim the air guard, s, as arranged on the upper smoke flueand with respect to the air register and discharge pipe thereofsubstantially in manner as specified.

In testimony whereof I have hereunto set my signature.
